SaaS development at UniqueSide ships full-stack SaaS products in 15 days starting at $8,000 fixed price, with auth, Stripe subscription billing, admin dashboard, customer dashboard, and APIs included. Every SaaS we ship is production-ready for paying customers on day 15, not a prototype.

## From MVP to Growing Product

We start with your MVP. Auth, payments, core features, deployed and ready for users. As your SaaS grows, more users, more features, more complexity, we stay on as your technical partner.

Two of our SaaS clients came from FAANG. They knew exactly what they wanted to build. They needed a team who could execute at their standard, fast.

## What's Included in a SaaS MVP

- Landing page
- User authentication and authorization
- Stripe billing and subscription management
- User dashboard
- Core product functionality
- Database design and implementation
- Deployed to your infrastructure
- Full source code handoff
